Eggs often come up in reproductive health discussion. This time we’re talking about dietary eggs, as in omelettes, and the role they play in boosting testosterone. The hormone boost from eggs comes primarily from the yolks, which are rich in dietary cholesterol, mono- and saturated fats—nutrients once demonized by health experts that have since proven to positively influence waistlines and hormone-health. In fact, studies on vegetarian and low-fat diets both show reduced testosterone levels of about 12 percent. Where higher fat diets of at least 40 percent of calories, with a higher intake of saturated fat, show increased testosterone levels. Why? It’s not rocket science. After all, cholesterol makes up the building blocks from which testosterone is formed; without it, the hormone simply can’t synthesize. Organic eggs are one of the best dietary sources. In addition to essential fatty acids, a whole egg is rich in aspartic acid, an amino acid that triggers production of testosterone.
Bilirubin is a breakdown product of hemoglobin. Red blood cells contain hemoglobin, which is broken down into the components "heme" and "globin." Heme is converted into bilirubin. Albumin carries bilirubin to the liver, where most of it is conjugated with a glucuronide before it is excreted in the bile. Conjugated bilirubin is called "direct bilirubin;" unconjugated bilirubin is called "indirect bilirubin." Total bilirubin equals direct bilirubin plus indirect bilirubin.
